<title>Problem 1000. -- A+B Problem -- 衡阳八中OJ离线版-2012-02-29</title><center><h2>1000: A+B Problem</h2><span class=green>Time Limit: </span>1 Sec&nbsp;&nbsp;<span class=green>Memory Limit: </span>10 MB<br><span class=green>Submit: </span>3194&nbsp;&nbsp;<span class=green>Solved: </span>2136<br>[<a href='submitpage.php?id=1000'>Submit</a>][<a href='problemstatus.php?id=1000'>Status</a>][<a href='bbs.php?id=1000'>Discuss</a>]</center><h2>Description</h2><div class=content>Calculate a+b </div><h2>Input</h2><div class=content>Two integer a,b (0<=a,b<=10)</div><h2>Output</h2><div class=content>Output a+b</div><h2>Sample Input</h2>
			<div class=content><span class=sampledata>1 2</span></div><h2>Sample Output</h2>
			<div class=content><span class=sampledata>3</span></div><h2>HINT</h2>
			<div class=content><p>Q: Where are the input and the output?<br />
<br />
A: Your program shall always <font color=red>read input from stdin (Standard Input) and write output to stdout (Standard Output)</font>. For example, you can use 'scanf' in C or 'cin' in C++ to read from stdin, and use 'printf' in C or 'cout' in C++ to write to stdout.<br />
<br />
You <font color=red>shall not output any extra data</font> to standard output other than that required by the problem, otherwise you will get a "Wrong Answer".<br />
<br />
User programs are not allowed to open and read from/write to files. You will get a "Runtime Error" or a "Wrong Answer" if you try to do so. <br />
<br />
Here is a sample solution for problem 1000 using C++/G++:<br />
<pre><br />
#include <iostream><br />
using namespace std;<br />
int  main()<br />
{<br />
    int a,b;<br />
    cin >> a >> b;<br />
    cout << a+b << endl;<br />
    return 0;<br />
}</pre><br />
It's important that the return type of main() must be int when you use G++/GCC,or you may get compile error.<br />
<br />
Here is a sample solution for problem 1000 using C/GCC:<br />
<pre><br />
#include <stdio.h><br />
<br />
int main()<br />
{<br />
    int a,b;<br />
    scanf("%d %d",&a, &b);<br />
    printf("%d\n",a+b);<br />
    return 0;<br />
}</pre><br />
Here is a sample solution for problem 1000 using PASCAL:<br />
<pre><br />
program p1000(Input,Output); <br />
var <br />
  a,b:Integer; <br />
begin <br />
   Readln(a,b); <br />
   Writeln(a+b); <br />
end.</pre><br />
Here is a sample solution for problem 1000 using JAVA:<br />
<br />
Now java compiler is jdk 1.5, next is program for 1000<br />
<pre><br />
import java.io.*;<br />
import java.util.*;<br />
public class Main<br />
{<br />
            public static void main(String args[]) throws Exception<br />
            {<br />
                    Scanner cin=new Scanner(System.in);<br />
                    int a=cin.nextInt(),b=cin.nextInt();<br />
                    System.out.println(a+b);<br />
            }<br />
}</pre><br />
Old program for jdk 1.4<br />
<pre><br />
import java.io.*;<br />
import java.util.*;<br />
<br />
public class Main<br />
{<br />
    public static void main (String args[]) throws Exception<br />
    {<br />
        BufferedReader stdin = <br />
            new BufferedReader(<br />
                new InputStreamReader(System.in));<br />
<br />
        String line = stdin.readLine();<br />
        StringTokenizer st = new StringTokenizer(line);<br />
        int a = Integer.parseInt(st.nextToken());<br />
        int b = Integer.parseInt(st.nextToken());<br />
        System.out.println(a+b);<br />
    }<br />
}</pre></p></div><h2>Source</h2>
